HORATIO H. C. KELSEY, OF NEW YORK, N. Y.

VALVE3 son.y HYDRANTS.

Specification of Letters Patent No.

To all whomz' may concern a Be it known that I, HORATIO H. C. KEL- sEY, of the city, county, and State of New p water, (viz:)` `the water that is in the pipe York, have invented a new and Improved Surface Valve for Hydrants; and I do hereby declare that the following is a full and eXact description.

The nature of my invention consists in making a circular surface valve for letting on, and off, the water from hydrants or any other apparatus, the surface valvebeing soconstructed as `to out the water 0H with much more ease than the ordinary faucet, or cock, thereby preventing in a great` measure the reaction of the head of water back on thelead pipes which invariably bursts them; also in providing said surface direction of the circular recess forming a passage E E which `carries off` the waste connected in thepart marked B which Ais the egress passage so as to prevent freezing. Fig. 2 1s a section showing the ingress passage A, where the water enters from the` `main into t-he chamber marked I-I H, and

pressing the valve tighton the leather makes a perfectly tight valve. The "water then passes through the aperture D, and up through the egress passage B, B, and olf through a leadpipe to the `top of the hydrant casing. y

C, C, C, shows the circular valve which is moved by a handle to be placed at the square a Fig. 3, shows a separate view of the valve C, C, C, for the purpose of showing the main aperture D and also to show the circular recess forming a passage E E which carries off the waste water from the egress pipe above described thereby preventing the water from being frozen. Now it will be readily seen that by the water enteringfrom the main through the passage A A and into the chamber II H there will be a pressure upon the back of the valve C C which will thereby be kept tight against the leather Vfacin' F F.

(M The water is letton through the aperture in the valve marked D D in sectional drawing Fig. 2 andthe drawingof the valve Fig. 3 so that the water passes up through the egress passage B B, and olf through a pipe to the top of the hydrant. By turning the valve back one quarter of a revolution the aperture will be thrown back in the position shown by the dotted lines marked D in Fig. l, andthe circular recess` forming a passage `E E 4 brought opposite the main passage thereby conveying the waste water that intervenes between the egress and 4the valveback through a small hole in the'.

back `ofthe casing and thence into the cesspool thusV preventing freezing in the winter. VhatI claim as my invention and desire to secure by Letters Patent is The general `arrangement of the surface `valve in combinationwith the circular recess forming a passage for letting off the waste water marked E E `and is fully shown and setforth in drawings and specification,

HORATIO II. C. KELSEY.
